PAGE BUFFER MANAGEMENT METHOD AND DEVICES PERFORMING THE SAME CAPABLE OF USING LSD PAGE DATA STORED IN A PAGE BUFFER AS IT IS

摘要

PURPOSE: A page buffer management method and devices performing the same are provided to guarantee a validity of data.;CONSTITUTION: A page buffer(50) stores LSB (Least Significant Bit) page data which will be a program on the page. A control block(80) enables the page buffer to maintain the LSD page data until a MSB(Most Significant Bit) page data corresponding to the LSD page data is programmed on the page. The control block includes a determining circuit(82) and a control ciruit(84). If the determining circuit determines a successive programming of the MSB page data, the control circuit releases the LSB page data stored in the page buffer.;COPYRIGHT KIPO 2011
